Description

Technical Field

[0001] This utility model belongs to the technical field of rotary kiln flue gas denitrification equipment, and specifically relates to an integrated rotary kiln flue gas denitrification machine based on polymer denitrification. Background Technology

[0002] Moisture problems typically stem from environmental humidity and insufficient drying of materials during transportation and storage. Particulate materials, especially in humid climates, easily absorb moisture, leading to agglomeration and adhesion within the hopper. Over time, this agglomerated material accumulates during transport to the spray gun, eventually clogging the nozzle. This not only directly affects the spray gun's performance but also reduces denitrification efficiency, potentially causing equipment malfunctions and downtime. Conventional methods to address this issue include enhanced material drying to reduce moisture content and improve flowability. However, these methods have drawbacks. Enhanced drying requires additional energy and time, potentially impacting overall production efficiency and economic benefits. Therefore, we aim to design a novel rotary kiln flue gas denitrification integrated machine to solve this problem. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a rotary kiln flue gas denitrification integrated machine based on polymer denitrification, including: an outer cabinet 100 and a drying component 200. The outer cabinet 100 is equipped with a drying component 200 for drying polymer denitrification agent particles. The drying component 200 includes a hot air component 210, a drying cylinder 220, and a loading and unloading component 230.

[0027] The hot air unit 210 is installed on the right side of the drying cylinder 220 to continuously supply dry hot air into the drying cylinder 220 to dry the polymer denitrification agent particles inside.

[0028] The drying cylinder 220 is equipped with a loading and unloading component 230 for feeding and unloading materials. The lower end of the loading and unloading component 230 is located at the bottom of the drying cylinder 220. In actual use, the outer cabinet 100 is also equipped with a denitrification box, conveying pipe, spraying pipe, feeder, airflow converter, suction hopper and other structures to form a polymer denitrification integrated machine. The aforementioned denitrification box, conveying pipe, spraying pipe, feeder, airflow converter, suction hopper and other structures all adopt existing product models on the market. This is existing technology and will not be described in detail here.

[0029] Please see Figures 2 to 4 The drying cylinder 220 includes a mounting frame 221, a hopper 222, a motor 223, and an exhaust pipe 224. The lower end of the hopper 222 is equipped with a mounting frame 221 for fixing the hopper 222 inside the outer cabinet 100. The upper right rear side of the hopper 222 is equipped with a motor 223 for driving the upper and lower material parts 230. The upper front side of the hopper 222 is equipped with an L-shaped exhaust pipe 224.

[0030] As the first embodiment of this utility model, in actual use, the hopper 222 can be used as a temporary storage structure for polymer denitrification agent particles. After the polymer denitrification agent particles in the hopper 222 are used up, they can be refilled until the required storage amount is reached. The hopper 222, together with the loading and unloading components 230 and the hot air component 210, can not only heat-seal and dry the polymer denitrification agent particles, but also temporarily store them. Its compact structure allows the outer cabinet 100 to have the functions of drying and storing polymer denitrification agent particles without a large floor area.

[0031] Please see Figures 1 to 6 The loading and unloading components 230 include a driven wheel 231, a loading hopper 233, an auger feeder 234, and a support frame 235. The auger feeder 234 is provided with a loading hopper 233 at the lower rear side, and the loading hopper 233 is located at the rear side of the outer cabinet 100.

[0032] The screw conveyor 234 has a rotating screw conveyor installed inside. The screw conveyor 234 has a discharge port 232 at the lower front side. In actual use, the discharge port 232 is connected to the conveying pipe installed inside the outer cabinet 100. The hopper 222 is the drying and storage equipment for polymer denitrification agent granules.

[0033] The screw conveyor 234 has a feed inlet 236 at the front and rear ends of the bottom position of the hopper 222, and a support frame 235 is fixed on the upper outer wall of the screw conveyor 234.

[0034] The auger feeder 234 has a driven wheel 231 installed at the top of the auger inside. The driven wheel 231 is connected to the drive pulley at the top of the motor 223 via a transmission belt. The top of the auger feeder 234 is designed to be open.

[0035] The hot air component 210 includes a fan 211, a hot air box, an air duct 213, and a dispersion air duct 214. The air outlet of the fan 211 is connected to the air inlet at the bottom of the hot air box, and the upper side of the hot air box is fixedly connected to the lower end of the air duct 213.

[0036] The upper end of the air duct 213 extends into the hopper 222 and connects to the dispersing air duct 214. The dispersing air duct 214 is fixed to the upper outer wall of the auger feeder 234. The dispersing air duct 214 has a cavity inside and multiple evenly distributed air holes at the lower end.

[0037] As a second embodiment of this utility model, based on the first embodiment described above, by setting up the drying component 200, in actual use, if it is necessary to add polymer denitrification agent particles, polymer denitrification agent particles can be put into the feeding hopper 233 at the lower end of the feeding component 230 (this process can be done manually or by using an external pneumatic conveying device to transport through a pipeline, depending on the actual usage requirements). Then, the motor 223 is started, and the driven wheel 231 is driven to rotate through the transmission belt, which in turn causes the auger inside the auger feeder 234 to rotate (the motor 223 rotates forward when feeding and reverses when discharging). The rotation of the auger inside the auger feeder 234 will drive the polymer denitrification agent particles inside the feeding hopper 233 to gradually transfer into the hopper 222. When the polymer denitrification agent particles block the feed inlet 236 on the lower side of the auger feeder 234, the polymer denitrification agent particles will move upward through the auger until they reach the top opening of the auger feeder 234 and then fall downward.

[0038] At this time, the blower 211 continuously blows air into the heating box 212. After heating, the air is pushed by the airflow through the air duct 213 into the dispersion air duct 214, thereby drying the falling polymer denitrification agent particles. When the airflow inside the hopper 222 is large and the air pressure gradually increases, the air on the upper side is discharged through the exhaust pipe 224 (the exhaust pipe 224 can be equipped with a solenoid valve to control the sealing and exhaust process in actual use), and the dried water vapor is carried out. When feeding, the motor 223 reverses, and the auger reverses accordingly. The dried polymer denitrification agent particles inside the hopper 222 are conveyed downward through the feed port 236 and connected to the external conveying pipeline through the discharge port 232, so as to participate in the subsequent denitrification process. The setting of the drying component 200 can dry the polymer denitrification agent particles as needed, avoid the clogging of the spray gun due to the moisture of the polymer denitrification agent particles in the subsequent denitrification process, greatly reduce the equipment failure rate, and reduce the risk of equipment downtime for maintenance.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
